V-4 is a chromium - molybdenum alloy steel alum, which has the following features: 
 High wear resistance 
 High compressive strength 
 ? Good permeability of the overall death 
 ? Good toughness 
 * Death fire, excellent dimensional stability after tempering 
 ? Good resistance to tempering of

 Fine-blanking process, especially when thicker material to be machined, mold requires very high wear resistance and toughness, with such a fine red V4 steel die at 5 mm-thick sheet obtained excellent results. 


 The key parameters of tool steel 
 Mold Performance 
 * Depending on the application to choose the right hardness 
 High wear resistance 
 High toughness 
 Typically, the high wear resistance of die toughness are lower, and vice versa. However, in many cases, the best performance of mold, tool steels must have high wear resistance and high toughness. 
 VANADIS4 is produced by powder metallurgy technology, high-performance steel cold die steel, which has excellent wear resistance and toughness of a good combination. 


 Mold for the production of 
 ? Mechanical processing 
 * Heat Treatment 
 * Dimensional stability during heat treatment 
 ? Surface treatment 
 High-alloy tool steel is usually more difficult to process than low-alloy steel and heat treatment. Therefore, high-alloy tool steel mold production costs are higher. 
 V4 alloy composition is very balanced and refined by the powder metallurgy steel-making technology made it with AISID2 steel with similar mechanical properties and heat treatment processing. 
 V4 of the biggest advantages is the size when hardened and tempered all known stability than the current high-performance cold work tool steels have know better. Also means: VANADIS4 is the
